MATLAB Version Uninstallation Guide: Completely Uninstall MATLAB to Prevent Residual Issues and Free Up Storage Space

# 1. Uninstalling MATLAB - Overview

MATLAB is a popular numerical computing and visualization software widely used in scientific, engineering, and financial fields. When uninstalling MATLAB, consider the following:

***Uninstall Type:** There are two types of uninstallation: full and partial. A full uninstall will delete all MATLAB files and folders, while a partial uninstall only deletes the application itself.
***Impact:** Uninstalling MATLAB will delete all installed toolboxes, custom functions, and user data. Therefore, it is important to back up important data before uninstallation.
***Uninstall Method:** There are two main methods of uninstallation: using an uninstall tool or manual uninstallation. The uninstall tool provides a more convenient and thorough uninstall process, while manual uninstallation requires manually deleting all related files and folders.

# 2. Steps to Uninstall MATLAB

Uninstalling MATLAB is a relatively simple process, but it requires careful attention to the following steps to ensure complete uninstallation and avoid any issues.

### 2.1 Uninstalling the MATLAB Application

1. Open the Control Panel (Windows) or System Preferences (macOS).
2. Find "Programs and Features" (Windows) or "Applications" (macOS).
3. Find MATLAB in the list of installed programs.
4. Click the "Uninstall" or "Remove" button.
5. Follow the instructions in the uninstall wizard.

### 2.2 Deleting MATLAB-Related Files and Folders

After uninstalling the application, you need to manually delete MATLAB-related files and folders.

The MATLAB installation directory is typically located at:

***Windows:** `C:\Program Files\MATLAB\R2023a`
***macOS:** `/Applications/MATLAB_R2023a.app/Contents/MATLAB`

Where `R2023a` represents the MATLAB version number, replace it with the actual installed version.

#### 2.2.2 Deleting the MATLAB User Data Directory

The MATLAB user data directory stores user settings, preferences, and temporary files. This directory is typically located at:

***Windows:** `C:\Users\<username>\Documents\MATLAB`
***macOS:** `/Users/<username>/Documents/MATLAB`

#### 2.2.3 Deleting MATLAB Registry Entries

Windows users also need to delete MATLAB registry entries.

1. Open the Registry Editor (regedit).
2. Navigate to the following registry entry:
* `HKEY_LOCAL_MACHINE\SOFTWARE\MathWorks`
3. Delete the `MathWorks` subkey.

**Code Block:**

reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\MathWorks" /f
